3CX v15 tunnel to 3CX v14

[3CXNewbie]

Upgrading the UK system to V15 tonight. Will the tunnel to V14 break until the USA system is updated?

One would hope that this scenario had been taken into consideration with version 15. Over the past few years have been a number of version upgrades, involving customers, with multiple sites. In the majority of cases, it's not feasible to upgrade every site in one evening (or even one week), so I'm certain you won't be alone.

fyi - I have a v15sp1 / v14sp3 bridge running. No issues reported.
